fix: yt-dlp'ye YouTube cookie desteği ekle (bot-check bypass)

android player_client YouTube'un "Sign in to confirm you're not a bot"
duvarını aşmadı — Coolify sunucusunun IP'si datacenter olarak
işaretlenmiş. Kimlik doğrulanmış bir tarayıcı oturumunun cookies.txt'i
YTDLP_COOKIES_B64 env değişkeni (Coolify'da ayarlandı, repo'da yok)
üzerinden container'a taşınıp /tmp'e yazılıyor ve her yt-dlp
çağrısına --cookies olarak veriliyor.
